Plate No. 10 is a representation of a perfectly healthy coffin-bone, with the upper and lower pastern and navicular bones front, and reverse sides. The system recommended by the author is intended to prevent any pressure whatever on the wings of the coffin-bone. Anything that prevents the perfectly free action of the coffin-bone will cause “navicular disease,” and “ossified cartilages.” After a foot is pared, as recommended in this, so as to be easily expanded, the wings of the coffin-bone, which are the widest part, should be protected by a wide shoe, and there should be no pressure whatever on the heels.
No. 11. Fitting a Shoe to Remove Pressure from the Heel.
No. 12. Contracted. Natural.
